How to use your Watch as a Compass
To use your watch as a compass, one must think in terms of the ordinary clock face. That is, a round clock with numbers 1 through 12.
When you need a rough compass, simply point the hour hand (or the part of your watch where that hour would be if it wasn?t digital) at the sun.
Half way between that point and the 12:00 point on your watch points to the south. For example, if it is 8:00, point the 8 at the sun and south would be at the 10:00 position.
This will work, even if it is a cloudy day and you are not sure where the sun is. To find where the sun is, simply hold a pencil or stick upright over a light piece of paper or a lighter part of the ground or a light rock. Even on a cloudy day the stick or pencil will cast some kind of shadow.
As in using any compass, you'll need to keep rechecking which way is south. If you want to go east, simply go at a 90 degree angle to the right of south. North is opposite from south. West is 90 degrees to the left of south.
